Abstract
A process for the protective or decorative coating of a continuously moving metal sheet, in which the sheet, after having received its coating, is heated by electromagnetic induction in a tunnel oven in order to evaporate the solvents and to cure the coating. The solvents are continuously extracted from the chamber of the oven, wherein a gas at a temperature greater than the dew point of the solvents is injected into the oven and which is gastight and thermally insulated in order to keep the hot internal walls above this dew point.
